Current Question (ID: 18060)

Question:

$\text{The positive deviations from Raoult's law mean the vapour pressure is:}$

Options:

1. $\text{Higher than expected.}$
2. $\text{Lower than expected.}$
3. $\text{As expected.}$
4. $\text{None of the above}$

Solution:

$\text{According to Raoult's law, the partial vapour pressure of each volatile component in any solution is directly proportional to its mole fraction.}$ $\text{The solutions which obey Raoult's law over the entire range of concentration are known as ideal solutions.}$ $\text{The solutions that do not obey Raoult's law (non-ideal solutions) have vapour pressures either higher or lower than that predicted by Raoult's law.}$ $\text{If the vapour pressure is higher, then the solution is said to exhibit positive deviation, and if it is lower, then the solution is said to exhibit negative deviation from Raoult's law.}$
